“Marvel soy banter” is a vacuous complaint
people don’t like repartee and witticisms that aren’t funny and enjoyable. if the performers dont have good chemistry
people appreciate it when its done well. its barely even a trope because the contexts and applications of “banter” are ridiculously broad,
have you seen Star Wars which has Han Solo being sarcastic and too-cool-for-this for 3 whole films
like yeah, it can be poorly received if you don’t establish a character and earn the payoff of a half-joke like that, but that is not inherent to putting it in a movie.
